Abstract: Systems and processes for providing textual representations for a communication session are provided. For example, at least one audio input is received at an electronic device, wherein each audio input of the at least one audio input is associated with a respective priority level. A priority level of an audio input detected at a microphone of the electronic device is determined, wherein a highest priority level among the determined priority level and each received priority level corresponding to the at least one audio input is identified. A textual representation of a respective audio input corresponding to the identified highest priority level is obtained, wherein the obtained textual representation is displayed on a display of the electronic device.

Abstract: A method and apparatus of a device that uses a video jitter buffer to buffer the video frames for a received video stream is described. The device uses the video jitter buffer to estimate the delay variability of the frames and pick a target delay that will help harmonize the playback with minimal loss and delay. This is achieved by estimating the delay spread, which is the result of performing statistical analysis of the measured lags of the video frames received. The video jitter buffer provides target delay recommendation and reference frame information to the video player in order to anchor the playback and schedule the frames presentation time.

Abstract: A video playback buffer adjustment system is disclosed. The video playback buffer has a target size, measured in units of time of content, and includes a compressed frames queue and an uncompressed frames queue. The uncompressed frames queue has a minimum threshold queue size. If the size of the uncompressed frames queue falls below the minimum threshold size, then a next encoded frame in the compressed frames queue is removed from the compressed frames queue, decoded, and enqueued in the uncompressed frames queue. If a current size of the playback queue exceeds the target size plus ? (a hysteresis value), then a playback frame rate is increased, and a presentation time of one or more frames in the uncompressed frames queue is adjusted according to the increased playback frame rate. If the playback queue size is less than the target size minus ?, the playback speed can be reduced.
